fanotify: use both marks when possible

2010-07-28T14:18:55+00:00

fanotify currently, when given a vfsmount_mark will look up (if it exists)
the corresponding inode mark.  This patch drops that lookup and uses the
mark provided.

fsnotify: pass both the vfsmount mark and inode mark

2010-07-28T14:18:54+00:00

should_send_event() and handle_event() will both need to look up the inode
event if they get a vfsmount event.  Lets just pass both at the same time
since we have them both after walking the lists in lockstep.

fsnotify: cleanup should_send_event

2010-07-28T14:18:53+00:00

The change to use srcu and walk the object list rather than the global
fsnotify_group list means that should_send_event is no longer needed for a
number of groups and can be simplified for others.  Do that.

fsnotify: send fsnotify_mark to groups in event handling functions

2010-07-28T14:18:52+00:00

With the change of fsnotify to use srcu walking the marks list instead of
walking the global groups list we now know the mark in question.  The code can
send the mark to the group's handling functions and the groups won't have to
find those marks themselves.

fsnotify: split generic and inode specific mark code

2010-07-28T13:58:57+00:00

currently all marking is done by functions in inode-mark.c.  Some of this
is pretty generic and should be instead done in a generic function and we
should only put the inode specific code in inode-mark.c

fsnotify: take inode->i_lock inside fsnotify_find_mark_entry()

2010-07-28T13:58:54+00:00

All callers to fsnotify_find_mark_entry() except one take and
release inode->i_lock around the call.  Take the lock inside
fsnotify_find_mark_entry() instead.

fsnotify: rename fsnotify_find_mark_entry to fsnotify_find_mark

2010-07-28T13:58:53+00:00

the _entry portion of fsnotify functions is useless.  Drop it.

fsnotify: rename fsnotify_mark_entry to just fsnotify_mark

2010-07-28T13:58:53+00:00

The name is long and it serves no real purpose.  So rename
fsnotify_mark_entry to just fsnotify_mark.

fsnotify: put inode specific fields in an fsnotify_mark in a union

2010-07-28T13:58:52+00:00

The addition of marks on vfs mounts will be simplified if the inode
specific parts of a mark and the vfsmnt specific parts of a mark are
actually in a union so naming can be easy.  This patch just implements the
inode struct and the union.

fsnotify: include vfsmount in should_send_event when appropriate

2010-07-28T13:58:52+00:00

To ensure that a group will not duplicate events when it receives it based
on the vfsmount and the inode should_send_event test we should distinguish
those two cases.  We pass a vfsmount to this function so groups can make
their own determinations.
